Hi Ak,
Very ingenious.
It reminds me of certain track useage in another part of the world to Germany
I have 2 rail stuff, mostly North American (era IIIa Pennsylvania, Norfolk and Western).
Using Trix C track (mostly same geometry available as Märklin C track) I have often dreamt how I would do certain arrangements.

Such as double mainline tracks into three and the reverse after a few miles to allow passing trains (very common) using slim turnouts.

Because I do not have a 2 rail layout or room for one, I have never gotten around to trying what may be possible.

That is very cool Alsterstreek. You demonstrate that beautiful and complex track arrangements can be made with standard C track pieces. Brilliant!

At appropriate switching speeds those look very navigable to me. I will have to give those a try one of these days. ThumpUp

Regards,
Jim

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
I have models from Era I to Era VI, but I try to focus on Eras I & III. Whoops, that one got away from me. Let's just say I focus on cool trains, regardless of the particulars :-)
So many trains and so little time.

Then a track inventory might be helpful.

One idea, two crossings.

24649 crossing: The curve is a 24224. The short straight pieces are 24064.

24640 crossing: The straight track in below configuration requires the intervention by a saw. I used the customised track piece presented in post no. 288 extended by a 24071. The curve is a 24224 which could be replaced by a 2461x turnout.

Ave H,

nice to see that you are still around trains ... but thought you had switched to DDC ... >;))))

well my bad, have not been to Tante M user.net for a long time, happend to my Modelltrains and FM too ...

now I am back again, hope to start my layout this year (if the buck will clear for good) with Rocrail & a lot of trains ... but not FM that's old history.

have fun ... I do ...
the one who rarely leaves the cave ... >;)

I have come across a post in stummiforum that may be of interest:

You can find there a pdf to download and a couple of links.
Enjoy!

The Märklin track geometry for parallel main lines has a separation of 77.5mm when using the short turnouts such as 24611/2.
The separation when using the long turnouts such as 24711/2 is 64.6mm.

The following is a basic geometrical device to progress from 77.5mm to 64.6mm between parallel tracks.
It is achieved through a 90° curve which I used quite a few times in my layout design.

The outer track starts with a 24064 piece straight.
The inner track starts from the same start perpendicular with a 24077 straight.
Page 41 of the booklet supplied with starter sets explains this.
